It is never too late to start .For learning is a lifelong process. There will be always new things to learn till the day we enter the grave..keke! It is not about early or late but it is about you, your interest and your motives. A late comer may learn more things than an earlier person because the late comer has got the zeal and the drive to search for the newer things and his learning curve maybe perpendicular rather than a slow up slope or flattish.
If you had blogged earlier , you may not have that advanced technology or information . So everyone is equal as new information is being produced everyday.

It is not about how much you know ,but how you apply those knowledge that you have in your everyday life that counts.

Nothing is ever wasted, it is only unused but someday in the future ,those you acquired or learnt will be relevant.Experience is always a good teacher.
