I am still very young, but I can feel the older you get, the faster the time passes. I see my four younger siblings growing up to young adults, getting married, having children and my parents slowly getting older. Their faces and bodies full of marks of their lives.
If there is one thing I have learned in my life so far, it is to follow your heart. Yes, yes this must sound very annoying to the most of you, it's so cliche and mostly not possible, you would think. Think again! Of course some things won't happen over night. They require preparation and patience. You don't have patience? Well, no wonder you feel stuck where you are, feeling sorry for yourself ever day. Are you waiting for someone to take your hand and bring you where you want to go? Are you waiting for some kind of sign or miracle to come? Don't just sit there, act! It's all in your head. It is your decision, whether or not you will finish your college, get rid of the 20 extra pounds you have or travel the world. Easier said then done? Of course! If the greatest things in life are so easy, well they would not be so great, right? All you need is some will power, motivation, passion. Live your Life, don't just waste it. Whatever you do, make sure it is what you want to do, and not because you think you have to, or you feel its your responsibility because that's what people around you expect you to do. If your partner is in the way of your happiness, you might ask your self, if that person is the right one anyway.
Of course your surrounding or situation will have an effect weather or not you can do this or that. I can not go travelling for two months, because I don't have the money. Save money. Have a close look on your expenses.
I can not become a doctor, because I can not effort the tuition? Go to libraries and study the medical books there, try to get a sponsorship.
Always try your hardest and see where it takes you. The biggest obstacle to overcome is yourself.
