Failure

Those that have not failed have not tried hard enough.
Learning means venturing outside our comfort zone and possible knowledge, to do that takes courage and to do that you need to be able to deal with failure and to learn from it.
In the same manner you need to respect those around you that also fail, there are teachable moments every day , teach- learn.
Do not wallow in failure or in the negative, shake it off and if you are in a toxic environment then recognize that too and if you have to readjust then do so. Staying in a unhealthy environment will bring you down and if you are not respected it just plain is not worth it.
