Life, which includes:
Pregnancy. Ugh tell me about it, I'm not in a hurry to have babies and don't really care if some of my friends are already pregnant with their second child. Doesn't bother me at all but why does it bother other people so much that I don't have a child just yet? People have different set of priorities and please respect that.
Relationships. Take things slow. Embrace the special people you've been blessed to know.
Education. Professors and people with Doctoral degrees / Master degrees go for higher education because that probably is their passion and their own personal goals. If your passion is elsewhere, does it make you look average or stupid? Definitely not. Search for your purpose and do as best you can.
Wedding and Marriage. It's about finding the right person to spend the rest of your life with and finding that person has no expiration date.
Live your life, it's filled with opportunities, hardships, heartaches and will test our courage. Once again, Life's a journey, not a race.
