Every thing can be achieved

Yes, very true anything can be achieved only if we have that intention and dedication towards our goal.

Self Development experts say, with the 3 Ds, that is Dedication, Devotion and Determination, anything can be achieved.

If we have Enthusiasm so we can do anything..

I agree with you. As long as that Child like enthusiasm and eagerness to know. We can achieve anything.
