It's just as important to know what you don't like as it is to know what you do. Try everything once, and continue doing those you enjoy or find worthwhile.
There will be a job out there, somewhere, that is more suited to you than you can imagine. It may not be the first, but have patience. Even if your first internship or job isn't perfect, take it as a learning experience and absorb everything you can. Never take an opportunity for granted.
Find a community of "your people" and devote yourself to that community. Take your time and try different organizations to see what suits you, but when you find "your family", that group of people who get you and enjoy similar interests, stick with it and feel accountability for its growth and success. You don't have to be the President - just take pride and dedication in something greater than yourself.
To any girl wanting to make a difference, set yourself apart, or follow your most personal dreams: Your most powerful asset will always be confidence. The path to growth and achievement will never be easy or comfortable, but be confident in all that you do. You have so much to give, and you are capable of it all.
