My life is meaningful because there's so much to be grateful for, just the fact that you have the ability to write, feel, touch, smell and see is enough.
There's so much to do in this life, so many challenges to overcome, people to meet and experiences to be had.
Embrace every part of life even the downtimes, the sad times, the times the you wish things were different, ask yourself this question when facing a challenge "what is this teaching me?", "What can I learn from this"?
Don't ask for life to be easier, ask for you to be better, don't ask for less challenge ask for more skill, wisdom.
Nature doesn't create a storm that last a lifetime, the sun always comes out.
