Your twenties are some of your best years when you truly learn who you are, what you desire, and what you're passionate about. In your twenties, you need to make mistakes; making mistakes not only teaches you lessons but also shows you what you are good at.
Every mistake, believe it or not, has a positive side to it. You also need to find who you are. This is a key factor of your twenties; aside from the growing you will do beyond your twenties, you grow so much in your twenties. Spend time in your twenties discovering yourself, your likes and dislikes, what you find appealing and not in people, what your preferences are, and what your interests are.
Find new hobbies that will mold you more into who you want to be and show you things you never thought you would like. Find the toxicity in your life and remove it; letting the toxicity stay is allowing the toxicity to win. Find the toxicity and don't allow to have a hold on you any longer. Find the things that make you a better person and do more of those things; volunteering at a humane society or soup kitchen are great ways to do this. Find someone to mentor or find a good leadership opportunity.
Spend time with your family, especially during these years, because you are becoming yourself during these years. Spend a lot of time traveling, whether it is to somewhere else in your state, another state, or another country; introduce yourself to different cultures and lifestyles of different places. Find something to believe in and grow in that; I'm a Christian and one of my focuses is strengthening my faith daily. Make plenty of memories during these years and make these years great.
Live your twenties to the fullest and don't look back!
