Happiness is inseparable from who you are at this moment in your life.
Who you really are is nothing but happiness itself.
So all you need to do to feel happy all the time is to develop mindfulness by knowing yourself.

To do this, you need to live in the present, without thinking about the past and future.
Associate happiness with as many things and people as possible. Don't get hung up on just one thing.
Always count your successes, not your problems.
Observe the ordinary objects in everyday life, as these little things make a huge difference.
Don't expect anything from anyone, even from your closest people. Expectations hurt and ruin your dreams.
Besides this, acquire a positive approach to life and don’t live in negativity.
Keep learning and growing and eventually you will feel great.
If a person decides to be happy, then nothing can stop him from doing so.
