I just started a full time job and got my 401k benefits. I just turned 25. I am financially stable. I do not have anything in my 401k. I was wondering if its good idea to put 75-85% of my pay check to 401k for the remainder of the year 2015. In January I will go back to 10%. Is there any benefit in doing this? or should I just stick with 10%?

Any other cool investment suggestions would be great from all you smart people as well :) 

Thank you
