My first advice would be to not underestimate the importance of sleep. This is a key factor for both quality of life and productivity. The only way to optimize sleep is to sleep enough.
Second, try to understand the power of compound interests as soon as you can. Life is long enough to invest and see the returns. Invest in yourself and in projects with long-term value, don't be seduced by shortcuts and don't be a slave.
Last thing, there is a lot of blind and seemingly unjust randomness in life, it is better to embrace it.
I've "slept enough" for a couple of years and developed a severe case of insomnia. I couldn't fall asleep till 2-3am, then slept till 10am to make up for it. Repeat. Bad idea.
Waking up at a regular time and restricting my sleep below what's comfortable has helped very quickly. I'm considering sleeping more, but feeling slightly groggy after sleeping 6.5 hours is way better than spending 10 hours in bed, 3 of them suffering.
Good point wrt unjust randomness, I'm terrible at embracing it. Any tips?
"Insomnia" can even be a sign of healthiness. It is often to see people experiencing a smaller need sleep while on ketosis/low-carb diet. I've been sleeping 5-6 hours every day for the past 2 years and although it bothers me (because I liked to sleep a lot and still enjoy it), I don't feel tired all day. Usually I also take a 30minutes nap around 1pm.
