Someone asked me what is it that prevents me from pursuing my dream. It's nothing, really. It's just that sometimes, you need to see and accept that a dream is just...dead. And carve yourself a new life. Pursue a new dream. Because if you keep hanging on to the same dream all your life and you never get to make it come true, you will be disappointed and turn bitter. So, maybe the most important thing is to know when to let go. It's good to dream. But maybe at some point it's just as good to see things for what they are and come back to earth. One moment a lucidity every now and then will not kill your dreams, but will actually allow you to see things clearly. And decide if you want to pursue this dream or another one.
I know people who wanted to be something great. Yet somehow they never had in them what it takes for that. And they never realized that. Because sometimes your dreams are far-fetched. Not everyone can be, say, a doctor, or a painter, or a dancer. What if I wanna be an artist but I have no talent? Will I choose to be bad at it just because that is what I always wanted to be, or will I face the hard facts, the 'sad but true' part and just be what I can be?
It's really hard to give up on a dream you've cherished for so long, but it is so much better to set a new goal and in the end actually achieve it. The chase may be good, but would you risk spending all your life chasing a dream that never comes true? What will you look back upon then when it's all coming to an end?
Happiness is also dependent on the goals you set for yourself in your life. While it is so great to dream, it is just as good to be realistic.
