Learn from someone who has already been up there: no matter how unique you feel, there is always someone who has had the same dream before you and ended up leaving marks that can make your journey easier; places to hang the rope, trails, broken branches to make the walking easier. The climb is yours, so is the responsibility, but don't forget that the experience of others can help a lot.
You may not control all the events that happen to you, but you can decide not to be reduced by them. Try to be a rainbow in someone else's cloud. Do not complain. Make every effort to change things you do not like. If you cannot make a change, change the way you have been thinking. You might find a new solution.
