If you don’t believe in yourself you won’t achieve even the smallest goal in your life!
Do you want to achieve something really hard? My recommendation is to don’t listen what other people think about it. If it is very hard, just few people have achieved it, so all recommendations around will be pessimistic.

Why do you need to have pessimistic opinions around you? That will just lower you self-confidence and that is the last thing that you need to achieve something really hard. 

You need to believe in yourself, you need to find the right motivation for yourself. Make it exited for yourself, think about it in the way you achieve it or it is everything over. You win or you win! Forget about possibilities to go back. Go for it and don’t look behind. Manipulate yourself, control your mindset, measure how close you are to succeed at it, give pleasures to your mind on the way that you will be getting closer to your goal.

What is clear is that you are going need to make sacrifices, but I ensure that if you really want achieve your goal it will be worth at the end! You will have self realisation and that is the most important someone could have in his life.

It is important be able to concentrate at it, avoid distractions, know your priorities and again say to your self: I can do it! Find the right way and don’t be scared, as harder is the goal, major pleasure you will have at the end!

No one else can motive you better then yourself!
