People say, to grow, you need to get out of your comfort zone.
Sometimes, you should.
Because getting out of your comfort zone will help you learn and grow from new experiences.
But I don't think you need to learn and grow all the time.
When all we seek in life is to be able to live comfortably.
Why bother making life uncomfortable?
Whether you choose to seek new challenges and leave or to stay in your comfort zone, it's all up to you.
Because what's important is to do it for yourself.
Please don't do it because others are doing so.
Please don't do it because they expect you to do so.
Do it because you want to.
Do it because it gives you joy.
But then again...
Who says that you can only have one comfort zone?
Who says that your comfort zone is limited?
What if you can expand your comfort zone?
You can start to pick things up little by little, and learn new things while you keep doing what you've been doing.
Life is not zeroes and ones. It's flexible, but only if we allow it to be.
Only you can answer.
But here's a suggestion:
Stay, as long as you enjoy your life.
Leave when it no longer gives you joy.
Expand, when you are not sure.
