Some people find it hard to be happy, there's always one issue with them. From peer pressure, to family issues and body image issues.
We worry that we don't fit in and can't seem to hold a conversation with other individuals(people we feel, are too cool).
We worry that people won't like our idea, so we stay in our shell for fear of rejection. And then we get sadder, when we see others thriving, were we failed to try.
Life is complicated. We live in a fallen world and pressures are ever present. There's always a reason to worry and one becomes sad because of these issues. Too many expectation from folks and you end up feeling bad, when you can't meet up.
As kids we had virtually nothing to worry about. We all looked to our parents for help, they fought our battles. Even when we got into trouble, it didn't take much time for us to forget all about it. And now as adults there's so much to do, bills to pay, decisions to be made, work to do.
Don't lose yourself in your pursuit of happiness. People go after things they feel will make them happy, only to find that they are still sad after getting it. Sometimes we don't even realise that happiness was right there. Learn to enjoy life and cherish the moments when you are around the people you love and you are just so happy. Find your happy and always hold it close.
But in all this, learn to love yourself first. Because if you can't be happy by yourself, you can't be happy with others around.
I may be wrong, but this just my two cents. And i got God helping me calm the storms in my life, so i'm happy.
