All great advice.
Another thing you can try is to focus on quieting the mind (as mentioned, meditation is a form of this...but I mean all day long). Our ego places thousands of thoughts in our mind all day long to keep us distracted, fearful, insecure, etc. (that is, it does so when you let it).
Reality is we really only need to 'think' for a short percentage of the time. All other thoughts are mostly of future and/or past events. Any thought of times other than now are wasteful thoughts and only hurt you -- keeping you attentive to the perpetuating illusion that times other than now exist (and that you are capable of being hurt, and that scarcity and unhappiness exist, etc.).
When you are in the now there is nothing but pure joy. Joy, wealth, abundance are eternal; the universe is infinite.
So really focus on quieting the mind. In time it will become second nature. Fact is you shouldn't have to 'try' at all. When you have to 'try hard' to achieve something it means that your sub-conscious and conscious mind are incongruent in their beliefs. The conscious mind, in fact, has limited power in its ability to control your actions. Most of our actions are controlled by the sub-conscious (we are effectively on auto-pilot most of the time...whether we think so or not).
It is our deep routed beliefs in the sub-conscious that project our goals to the universe -- which manifest in the physical world. That is why will power is an illusion. As already mentioned in a previous post, you must change your expectations and ultimately what you really, really, really believe in. If your physical reality doesn't present itself the way you would like it to be -- it demonstrates you have blockages and limiting beliefs and expectations in your sub-conscious.
Trying hard actually tells the universe that you are scared and fearful that you will not attain your goals. And as we all get what we ask for in this world (free will is eternal), the universe gives us exactly what we focus our mind on (if you focus on being scared you will attract more scary situations and thoughts).
You must first be clear on what you want and then just let go and be faithful that the universe will deliver. You must be that your goals have already been achieved. Because ultimately they have (your spirit has everything already). Being is having and the universe always gives you more of what you already have. You simply just have to decide that you already have it (deep down, regardless of physical reality).
To clear blockages even quicker, try using an energy clearing technique as well. EFT is a great one. You can also use EFT for physical ailments. All pain (mental/physical) represents a mis-alignment of your energy patterns.
