The road is undefined and hard. Guidance is scarce since it’s your quest. You might get lost. You might even forget who you are, who you want to become. Your goals might become vague. Changing the world is an overwhelming task. Having a myriad of options, getting lost is eminent.
I’d say go back to basics. Go back to certain principles that you know about how the world works. Go back to those things about you that you love, appreciate and think that they define who you are the most.
Most importantly, have the courage to work up from there and commit yourself to certain actions and decisions that you feel come out from who you really are.
