If you are feeling stagnant, it is because you are not growing, giving, or renewing your intellect.
If you continue to grow and work on yourself, you will always be evolving and accomplishing new things.
If you keep giving, you will make others happier and help others to grow. By giving you will also be growing as a person and become more of a giver.
Growing and giving is also a key to happiness. The soul loves to grow and the soul loves to give.
Renewing your intellect mean that you should be reviewing what you know or what you used to know that you forgot. We take in a lot of information every day. If you are a person who reads or listens to personal growth audios, you are constantly learning new information. How much of it are you putting into practice or renewing every day? If you are not renewing the information and putting it into practice, nothing will change. If nothing is changing in your life, you will feel stagnant. Human are meant to grow and evolve.
