When I was 18 I was amazed by some of the programs that people my age put together and I constantly compared ages believing that I should be able to compare with any my age without putting any effort behind it. Even if I wanted to accomplish something similar, a voice inside me said that I still not had the basic knowledge needed to even start. I'm now 28 and can say that I have in very few ways moved towards these goals.
I have yet to fully break out of this loop, but now I know what tools I need in order to do so. Break the bad habits, by replacing the actions that lead to a goal with better ones. Realize that instant gratification serves little purpose beside delaying you even more on you way to the real goal. Really focus on areas and put some real time behind the goal in order to have a chance of finally getting there.
Our daily motivation is limited, so stop spending it on getting nowhere with everything that remotely interests you and get somewhere with something.
Also: exercise, get some sun and spend some time alone (no friends, music, podcasts, audiobooks or electronics) with your mind every day.
