Most of the time frustration is the result of failures and regrets so you should not set unrealistic goals for you. Be realistic and live in the present instead of staying in the past or future. You must realise that everyone blunders so it is normal to be unsuccessful.
Though, it is good to look for the reasons of failure but it is not wise to mourn all the times. All you need is to think on what Shakespeare said,
“The robbed who smiles steals something from thief,
he robs himself who spends a bootless grief.”
Be nice to yourself:
Do not fall prey to self-cursing. Just be nice and kind to yourself. Stand in front of the mirror and praise your efforts. This will help you to feel confident and ultimately diminish the effects of frustration.
Mend your psyche:
Sometimes people want to control everything and get frustrated when it does not happen. If you are one of those then it is high time to get a grip over your desires. Just put all you have and leave the results to a higher power.
Sometimes impulsiveness and edginess work like a catalyst for frustration. You should develop patience and let things happen naturally.
Being content is very important to control frustration as you do not desire the thing which you don’t deserve and ultimately avoid disappointments.
Understanding the life:
You should understand that life is full of challenges and you cannot be victorious every time so just give it your best shot and surrender to the divine.
Visualise your goals:
Before starting activities, the first thing you should do is to visualise your goals. This will help you to evaluate your prospects and you won’t get disturbed in case of failure.
