Are you taking life too seriously? You can have fun, laugh, and enjoy life even while being productive and professional. Don’t take yourself so seriously. If you think about it, our life is but a blink of an eye in the grand scheme of this universe we live in. We are a spec of dust in this world. Don’t make yourself up to be more than what you really are.
That’s not to say that what you do in this life doesn’t matter. After all, you still should do the right things (provide for your family, be polite, etc), but if you can’t have fun, you need to reflect on what your life has become.
