no matter how bad time you are facing in life, things can always ger worse because this world is not perfect and absolute worst is impossible. So be grateful for what you have, because there will always be people who could only dream about what you have.
Training is nothing, mentoring is nothing, the only thing that counts is to take action. It is ok if you are failing at start, everyone does, just do not give up, you do not know what lies at the end, if things were so predictable then life would have been easy.
