It is absolutely fine to feel low at some point in life because it’s a part of human nature and emotional anatomy. We should not look down upon oneself during these low times and get discouraged.
Sometime spending a little time with your low mood or crying your negativity out in a room can help you empty your heart only to fill it again but with love and positivity.
Accept your situation and then work on it to bring that enthusiasm and zeal of your life back on track.
Not thinking much about these small failures, one should go ahead to the next step with confidence if one want to climb the mountain of life to conquer its peak of success and contentment.
According to Charlie Chaplin “Nothing is permanent in this wicked world, not even our troubles.” So why worry???
Be passionate and never blame others for what are your own failures.
Let us take the example of “EKLAVYA” who wanted to learn archery from dronacharya . But the guru refused to teach him. However Eklavya love for archery was so strong that he made a statue of dronacharya and learnt archery standing in front of the statue. Such was his passion for archery and respect for his guru that he cut his thumb and gave it to dronacharya as guru dakshina.
We blame external factors for our failures or sometimes merely give up saying that it is due to bad karma that we are unable to achieve our goals.
Lord Krishna (kaanha) tells Arjun in the Bhagavad-Gita : Work without reward in mind. You have a right to perform your duty but you are not entitled to the fruits of action.
