There needs a potential within someone to be criticised but nothing is needed to do the awful criticisms. So when we are getting criticised we must bear in mind that we must be doing something effective and that's drawing the idle minds who are busy after these meaningless criticisms.
There is a very popular proverb that says, "Failure is the pillar of success." Those failures we do on the path of achieving something shouldn’t be regarded as failures but as a chance for correction to do it better. A positive lesson on this but there will be some random people who are always after criticising these mistakes. They will surely be spreading that positive lesson in a negative way. They are the people who have nothing meaningful to do and that's why they are too idle to roam around and criticise others in a negative way.
These kinds of criticism are always discouraging. On our journey, we may face different difficulties and that's pretty normal. In such moments we need some positive pushes from the back instead of these negative ones. Negative ones only create more hindrances for us, making the way more difficult. Should we get demotivated? No way, this is a proof that you are working, doing something meaningful that isn’t too easy for everyone to do and that's why you are making mistakes. That's fine as long as you are determined on your way to learn from those mistakes and mend your ways otherwise there is no way of any argument. Talking about the people who are always on criticising have nothing meaningful to do and that's why they don't even know the worth of the task the person in front is doing. If they were aware of that then they would have done it in a good way, in a constructive way. Above I have mostly focused on the negative criticism. Let's dive into the constructive ones and that should be welcomed. The positive ones I have mentioned fall in this section. Some criticisms are done with a positive motive for us to mend the mistakes, figure out the failings in us. We can't always find out the errors in ourselves, we need to look into the view of others too. This is like our teachers saying, "You are good at math but very bad at Biology." This one is done in a constructive way, pointed out the good in me and also showed the lacking to where I should focus from now.
Personally, I face the most devastating one and that's self-criticism. Many times I face this on my way. Trying to do something I start criticising myself whether I will be able to do it or not. I get myself into dilemmas that the thing I am moving with will be beneficial or not. On mistakes, I start to blame myself over and over again and stick with that which creates mental problems. If we can't distract ourselves from the negatives within us on our own then no one can push us ahead.
So it has both negative and positive sides but all we need to do is stay positive from our sides and believe in ourselves and keep moving forward. If we get stumbled on those criticisms then that's a gone case.
