You want what you want now and try not to think about the future. So then, what happens when you think about the future? Do you freak out? Are you filled with regret? Or are you just happy?
There are so many times in your lifetime when you decide something that could change your whole life and you are happy about it, regardless of whether or not you thought about the future ahead of you.
What about if you decided to choose a path that makes you anxious and unsure now but you know there's a happy future for you?
At certain times in our lives we are forced to make a decision even if others are unhappy about it and you know what, if they can't support you then screw it!
