I believe everything is a state of mind. What I mean is, how you perceive things is a result of how you condition it in your mind .
When you condition yourself that Life is hard, then it will always be. No matter how many blessings you received, how many achievements you reached, how successful you become, but you keep telling yourself that Life is hard, then you will really feel that it is hard. However, even how broke you are, how tired you are of life but you never gave up and keep telling yourself that Life will be better soon, then it will be better.
To make life easier, forget about the negativity. No matter how bad the situation you are in, always look for its positive side. Always remember that there will always be rainbows after the rain. Meaning, after every trial you encounter, there will always be hope.
Another thing, be contented with what you have. For me, Contentment is loving what you have. Even if you have the oldest model of a car but you are happy and contented with it, then that car is all you need. Your perception that life is hard spawns from wanting more than what you have. Even if you own all the treasures in the world but you are not contented with it, you tend to look for more.
Then, surround yourself with positive people. If you are surrounded by positive people, their positive vibes will radiate to you.
And lastly, trust in God. If you put God in the center of your lives, you will not feel empty. Just trust in Him. Continue to do your best and He will do the rest.
