2. Accept the fact that you will always have a shallower knowledge than people that focus on specific things. Be humble, there will always be someone smarter in the room with knowledge on his favorite topic that you will not be able to match unless you dive way deeper than you are currently willing to go.
3. Realize that your drive for knowledge and understanding is actually a natural thing - I would argue that this is the case for most people, and while some have found ways to satisfy this "need" with random redirection activities (mostly "entertainment" and shopping), some have found "their thing" and are investing their energy into a specific thing - which sometimes is utterly useless (as in "useful for the greater good, humanity, or for someone") , sometimes can be turned into something useful for oneself or for others (e.g. "money in the bank").
4. As soon as you make your hobby your job, it is no longer a hobby, it is now your job. And for most people that means they no longer enjoy it nearly the same way they did before. A envy the few lucky ones where this is not true. You now need a new hobby.
5. Don't forget to enjoy life. If you found something that makes you happy, that is purely awesome! But also realize that you will have to do things that at the same time (1.) keep you from doing what you love, but (2.) also enable you to do what you love. Some people call it their "job". You need money and time, your family needs money and time, your hobby needs money and time. Find a way to sustain all that, so you can do and enjoy the things that make you happy.
