Take care of health, both physical & mental. Get regular checkups done.

Chase peace, not happiness or proxies of it.

Learn. Create. Lead. And be a lion, not a wolf.

Put extra caution on safety. Traffic, etc. Even with low probability of it happening, it's not worth it.

Create rituals. They put you in the zone. Both for your work, family, and friends.

Risk/Reward ratio. Simple formula: How big it can be * probability of it happening.

Know what makes you happy and be like a kid. Never let anyone talk you out of it.

Try not to compare yourself to others. World is freaking good at status games.

Keep your ego in check or it'll hit back hard when you need it.
