I think your mindset, your words, your reactions, and your choices shape your experience of life more than external circumstances do. As they emphasise awareness (what you say, think, and focus on), growth through challenge, gratitude, and the understanding that change and connection are essential to becoming a better version of yourself.
Here are 11 life lessons:

The less you say, the more your words will matter.
Don’t take everything personally as not everyone thinks about you as much as you do.
When you focus on problems, you’ll have more problems. When you focus on possibilities, you’ll have more opportunities.
No matter how much it hurts now, someday you will look back and realise that your struggle changes your life for the better.
You meet people for a reason, either you need them to change your life or you’re the one that will change theirs.
Never be afraid to change something new. Life gets boring when you stay within the limits of what you already know.
You’ll never truly know the value of the moment until it becomes a memory.
Once you begin taking note of the things you are grateful for, you’ll begin to lose sight of the things that you lack.
If you do not have control of your mouth, you’ll do not have control over your future.
Life is a mirror and will reflect back to the thinker what he thinks into it.
The only person you have to face in the morning is yourself. Be unbeatable.
