A valid point indeed, Praveen.
When you ask some doubts and you get a detailed explanation from your helpful and patient senior, you will be so happy and you prefer to be within that comfort zone. This comfort zone is actually a trap where you get stuck if you don't get others' help.
Instead, if you do your own research and analysis, you might not always be able to find the right solution. But, at least you will have a clear cut idea of the situation. You will always be able to find a launch pad from where you can start. You will only need some directions, which could be given to you by your seniors.
If you get a solution without any personal effort (other than irritating your senior), you will not get any kind of satisfaction from it. On the contrary, if you EARN your daily bread you will be able to feel the real taste of it.
When the going gets tough...the tough gets going..!!!
