The responsibility of working hard, shaping, and living a fulfilled and happy life falls largely on you. Do you acknowledge that? If you do, this basically means that from this point onwards, the burden of planning your adult life is on your shoulders. The sooner you understand this, the better! News flash, nobody, I mean nobody, even your parents, your spouse, your friends, is coming to save you and make you feel happy. Yes, they can be there to support you, but nobody else except yourself can change your life and make you feel fulfilled. The first thing you need to do is to ask yourself this question, "what can I do right now, this week, this month, and this year to set the direction of my life towards what I truly desire?
Sure, life is not easy, and there will be times when we'll feel completely drained and dejected after facing failures or rejections multiple times. However, you need to keep in mind that failures are merely lessons that will propel you towards HUGE success.
