Should Dhoni take a rest from cricket and improve his personal performance and i?

I fell Dhoni should take a rest from International Cricket and work on improving his own performance of batting and especially keeping too. Even Dhoni himself accepted in media that he is not able to clear the fence from a long time and he is working on it. Where has taht Dhoni gone who hit sixes frequently and who could increase the pace of innings, the same Dhoni is now involved in slowing down the run rate and increasing pressure on the coming batsmen amking them difficult to play fast in later stages.

Even he should work on his wicket keeping skills, for instances he should learn to collect the ball behind the stumps so that he can break the sticks easily during runout chances which he misses always as he stands in front of the stumps during the throw from the fielder. Frequently he misses to catch hold of the  catches and he is even slow in his stumping abilities.

And many faulty decisions in this world cup should also be assessed by him and the mistakes made should be kept in mind in future so he does'nt repeat the same again.
