The truth of the matter is that being over aggressive is like doing the right thing, the wrong way, because am very much aware that excess of everything is bad.
As an individual that wants to grow his or her stash of Bitcoin fast, the ideal thing to do is to be aggressive, but not when you are weak financially, because if you do it more than your capabilities, then that's where you are wrong, because you will definitely struggle to hold onto it on a longer run, when your emergency funds aren't capable of covering up for the shortfalls.
So in essence of what am trying to say is that if it's done the right way, it's good, but if it's done the wrong way, that's where the problem is, because you can't be investing money that is for your upkeeps and be expecting not to fall back to your investment at some point in the future.
To have a good portfolio, one needs to stand well on his two financially - it's essential due to the fact that your investment is like a garden of sorts - you can't reap what you sow if you don't look after it well, or if not enough time passed through.
And it all boils down to having a plan, a realistic one - combining it with patience and determination to make it through and right.
