Thoughts on life and love

I have come to the conclusion that 99% of people my age or around my age are extremely immature about relationships. There are a number of things that frustrate me about people and hearing them complain about certain things. First off, why do people think at the age of 19 or 20 that they will never find that "perfect" person. Of course you'll find that person; you're just starting your life, why can't you be single and play the field and just enjoy life first. You don't always have to be in a relationship to feel validated about yourself. After being in a relationship for a year and a half, I'm still getting used to being "single" but it's a good feeling. Just being able to to be free and have "me" time is validating for myself. I don't understand why people view being single as a bad thing. It's not. It's a time for self-reflection. It's a time to figure out what you want from the world. So stop complaining about being single and put that time to good use. You'll find someone sooner than you think.
Second of all, I don't understand why young people find it important to be in serious long-term relationships. I know I haven't been one to talk due to the past couple of years, but after reflecting I have discovered that being in a relationship like that didn't allow me to explore my full potential. Not that it was a bad relationship, just the fact that when you're young you should be concentrating on yourself and your own dreams. Things shouldn't be taken so seriously until you find out what you really want from life and are mature enough to make long term decisions. Things change drastically from one year to another, and we grow up in ways we never thought we could. And I don't know if it's just because I'm young, but I have recently come to the conclusion that there is no such thing as a "soulmate". I just honestly think we could be happy with a number of people. It just depends on the timing of each relationship and when we get ready to settle down. Think about your failed relationships and why they ended. In some form or another, they all ended because the timing was off. Everyone we meet and the relationship we form with them is about timing. Timing is everything in life.
