too much attachment with anything can cause too much pain/joy as well

Our life always seems to be fuelled by a goal, some desire and not to forget hope that we will accomplish them. In the process of working towards the goal, you gotta be very well determined. Quite often that determination can turn into an obsession. May be it is good to concentrate all your thoughts on one thing, but it shouldnt happen that 'that one thing becomes your life'. That is where you gotta strike balance. That is where you have to be wise and conscious in every minute you spend. You shouldnt let that desire to achieve your goal determine everything you do.
When your journey towards the goal has finished, and you were waiting for it to become reality,but suddenly someone(some external factors beyond your control) has blindfolded you and prevented you from seeing it....then,your whole life seems to have become standstill. Yes at that point of time there is nothing really happening, nothing seems to interest you, everything appears so boring, there is no motivation to do your daily chores. It is simply because you were so attached to that thing that helped you keep going...Is it impossible to come out of that situation, to resume your normal life ?? Well, wise people should be able to do that, because they constantly keep judjing what is good and what is wrong and always do the former. But for people who cant do that, it is advisable not to get too much attached to anything...You can still have a goal and do real hard work to achieve it, but your job should end there and the result for it is beyond your hands....the worst is you are not even sure if you would ever get the result.
