The thing about life is that everything is supposed to fall into a certain order. Society has a particular idea of normal or expectations you are assumed to meet. You are presumed to graduate high school, go to college, settle down and get married, have children, and live happily ever after. If your soul speaks differently of this stereotype you may be considered peculiar or weird. After all, humanity has too many expectations.
Why must everything be planned or rushed? Life is too short, why not live it adventurously? There is nothing wrong with not wanting to get married or having children. Don't get me wrong- anything can change. You may not want a baby today but you may want one next week. That is one of the curses of life (baby fever).
Who made the standard for life anyways? Be free. If your soul belongs on the road, in the air, or at sea, follow that urge and never let it subside. We only have this one life to live. Live it courageously. All we have is time, we must spend it wisely doing as our heart desires. Do not listen to society's expectations, they are nonsense. If you want to ride solo, then do it! If you are unsure about wanting children, then by all means, wait until you are positive you are ready.
Go explore, travel, find yourself. Please your soul and fulfill its needs. Do not rush life, let it play out. It is okay to want to be alone, regardless of what everyone else believes. This is your life - live it to please yourself, not others.
