Same with writing.. I love to write, I would like to at some time write a book, but I am to lazy to just start with it...

Why don't you write a short story instead of a book? Even if you did start, you probably wouldn't finish it without writing something of a comparable length before(like a failed book).

It sounds like you just want to write when you say you're too lazy to start with it. If you were going to write a book, you'd need to decide on an idea and do a lot of planning and research first. If you did that some time without any intention of actually starting the book, you could wait until you want to just write, which should be sometime soon, and start then. A good time to do some planning is when you don't feel like doing anything.

If you don't have any projects to work on when you want to write then you could write something quick and short instead. Doing that would help you write a book if you ever decided to.

I know that for example doing sports would be good for me because it makes me feel better, gives me more energy, and makes me mentally more sane. But everyday when I come home I rather sit in front of the TV or read a book, or browse online...

You should try to figure out which kinds of sports you like and what it would be like to play sports before you expect yourself to try to do them. If someone told you that they wanted you to go and play sports right now, you wouldn't be able to because you wouldn't know what they mean. You'd need to know which sport to play and where. What you should do is pick a sport and then set everything up so that you can come home and do it right away.

For example, you might decide that you're going to take a walk every day, which is one of the best exercises to do if you want to feel good and it's easy, but won't build muscle mass or improve balance or hand-eye coordination. You decide that, tommorow, you're going to go for a walk when you get home. So, you look at what the weather is going to be like tommorow, pick which clothes to wear, hang them on a chair near your doorway, and then get any equipment you think you'll need and put that on the chair too, like a watch, waterbottle, compass(in case you get lost), ect. Also, decide on an approximate route you're going to take with something like Google Maps, and pick a specific departure time if you need to do something once you get home before going on a walk. Put the chair in plain view of your doorway so that you don't forget that you're supposed to walk.

The next day, you would come home, get dressed, take the stuff, and leave. You can deviate from plans a little, like wearing something else or not taking some things, but the important thing is that you walk. During the walk, the most important thing is that you feel good. You need to consciously make yourself feel good about the fact that you're walking right now and talk to yourself about all of the good things this walk is doing for you right now and in the near future. You might head back if you really dread the walk before you do it. During the walk, you can't really stop or get distracted since you'll need to spend as much time as you've been walking going back, so it should be easy to do.

It's a lot harder to do something consistantly every day though, but you should be able to start by planning.

I relatively ok with myself, but I would like to improve because I know that it would make my life a lot easier. But how do you do that when you are lazy?

You said that you want to improve because it would make your life easier, so your objective would be to make your life easier. To me it sounds like you consider improving yourself something that you just have to do and haven't thought much about what would actually happen once you do it(and how exactly you're going to start improving yourself), which would make it painful to start doing.

To make your life easier you would really need to do something like increase the ammount of free time you have each day, and make your non-free time stressless. Free time would be defined as time during which you don't require yourself to do anything. This might involve improving yourself but the objective would be one of those goals.

First I'd make a schedule of how you spend your days by writing down what you do every day and for how long. After that, try to group non-free time into larger blocks, so that you don't have to shift between enjoying yourself and having to do something as much. It would also be beneficial to pad your schedule with free time before work or add some work in the middle of your free time to reduce stress so you might have to play around with it. Understanding yourself and learning about personal development will also reduce stress.

In the long run you'd want to reduce how much money it costs for you to live, how long you spend working, ect.

If your goal is personal enjoyment, you could give yourself things to do during your free-time block, figure out what kind of entertainment you like such as genres of music and video games and buy those, and set long-term projects.
