Wake up and set aside an hour for personal development activities (meditation, self-introspection, observing nature, etc.) Do the things that make you feel blissful, optimistic and empowered so that you can set a positive tone for your day. I guarantee that once you start doing this, your days will be more enjoyable and fulfilling. Today is going to be the best day of your life. Duh!!
Don’t take life so seriously!
Learn to laugh at the little things and this whole “existence” thing will be a whole lot easier. Be amused by your mistakes and failures and be thankful that you learned your lesson and won’t mess up like that again. And most importantly do things that you enjoy! Life is not strictly business, it can be mixed with pleasure.
