Accepting yourself is not something that you do, it's more something that you don't do. If you don't down yourself, you accept yourself. You have to have a nonjugdmental attitude towards yourself. That's about it.
We worry enough about what other people think about us, which is also completely unnecessary most of the time. Then we internalize this fear of what other think about us and are axious about what we do even if nobody is watching. It's completely pointless.
As Ghandi put it: "They can't take your self-respect if you don't give it away."
You don't need to acquire something to accept yourself and you don't need to do anything special. All you have to do is not down yourself for anything. In fact, it's best to completely forget about all these "self-issues".
If you don't think about them, they don't exist.
Stop believing that you have to do x, y or z to be a worthy human being. The thing is: You don't. The whole problem doesn't really exist. We made it up by confused thinking.
There's this Zen-book that starts with "My dog doesn't worry about wether it'll have a fulfilled life..." I like that line.
Similarly, you don't have to worry about wether you'll have self-worth or self-esteem. You just have it. You just confuse yourself by falsely believing that you had to do something special to earn it. You don't.
I've read this quote somewhere, I think it was in "Self-help stuff that works":
"Self-esteem is the opposite of self-consciousness"
This means that if you don't think about your having self-esteem or not, you have it automatically.
So the best advice I can give you is to forget the entire issue alltogether and just work on actual measurable real-world problems to improve your life. You'll be so busy, you will then over time realize that it wasn't a problem after all.
Or as Emerson (I think) said it:
"Do it and you shall have the power."
It's really this simple.
The entire problem of "self-esteem" is an illusion, an invention, a trick we sadly play on ourselves. I'm currently writing a blog about this problem, because I think it's taken such proportions, it's not funny. So if you still have any questions, please ask. It will help me improve my blog writing.
And since I'm already in quote-mood, here's a nice story:
"A young cat was constantly running in circles chasing its own tail. An old cat was watching it, slightly amused:
"What are you doing?"
The young cat replied: "I'm trying to catch my own tail. After I've caught it, I will be happy."
The old cat smiled again and said:"Well, I have done this, too, in the past. But then I've found that if I just walk wherever I want to go, my tail is following me automatically." "
