You have to trust the timing of your life. You might not have found Alladin's magical lamp till this day, in spite of all the efforts you've made. You might have to struggle to get anything and everything that you want, while someone else would be getting it served on a silver plate. But have you made a point to celebrate every little milestone because you know all the effort that it took? Or you just put it in your bag, and begin hustling further, because the ones around do not know all the effort that it took?
I may not know much, but I very well know that you are not meant to live a sad life forever. You don't deserve happiness followed by sadness.
"How do you ever know for certain that you are doing the right thing? This moment is nice, I'm enjoying, but what about the future?"
But what about the present?
Because, when all is said and done, it is your own life.
In the way of achieving and struggling, make sure you take out time for yourself, to appreciate the beauty around and the piece of art that you are. And you never know, that Magical Lamp would be lying just a turn ahead, to change your life for better. Till then, you've got to believe in yourself, and the timing of your life.
