My 2 cents .
1. Get fit , eat well , dont drink-smoke , buy kindle read a lot of books
2. (For upsc) dont go after the dramas , focus on pure basics ,dont run after complications , focus on PYQ , do MGP / Mains answer writing daily from day 1 , read hindu
3. Talk to people , get comfortable in making a conversation . Try to be humble but confident.
4.ensure diversification , be it in job ( eg do degree from ignou with prep), or in income source.
5. Dont be arrogant about your capabilities , life will push you so low just to prove a point , that no matter what you are god's will is supreme ,dont wait for life to teach you that lesson .
6. Explore a bit , trek , travel ,enjoy .think long term , be disciplined.
