"I am like this only"
And that very 'like this only' is the root cause for a lot of troubled times. You see it clearly, you realise it, you know for a fact. That. Is. The. Problem. But then, what can you do, 'you're like this only'!!
Why do some people love being unhappy? It's the easier way out sometimes, requires you to be lazy about your own life in some terms, but isn't it so much more difficult to continue to be in that state. It'll need effort to change that trait in you, that one thing that you realise is a cause for so many unhappy times. But then you would rather not. 'I'm like this only' qualifies as a reason for everything to stay the same today, tomorrow and forever. I hate how ubiquitous this sentence is.
Why is it so important that you stay the true you, even after you know there's a shortcoming. What does it even mean to say 'I won't be myself then’? It'll all be better for you!! Two extra steps and you would've reached the balancing point, you'll be a 'new' you, but still a 'true you' (whatever that means!). I can never get what’s the point in all the personality analysis, and knowing the real you, if someone can't work to overcome the shortcomings in themselves.
If you realise the problem, then why can't you solve it! At least try to!!
