I honestly believe life is way to short to hold grudges and to quick to miss opportunities, so be you and achieve the best you can without being envious of others.

I feel it is natural for most people to never feel completely satisfied with what they have in life. Its only human that we want to strive for the best but, don't forget what is important to you, always be appreciative for what you have because I am sure you may not like the opposition to that.

If you have a good life embrace it and smile, to be happy is the key to living a successful life <3
