Neil Nitin Mukesh, who turns 31 today, wants to concentrate only on his career this year

Neil Nitin Mukesh turns 31 today but feels he is yet to grow up mentally. Now that's some confession!

The actor who celebrates his birthday today thinks he is still 15-years-old.

Says Neil, `I am still the same child that I always was. In fact when I go to a toy shop with my nephews, I end up buying more stuff than them. I have four films releasing this year and it feels like I'm awaiting my exam results.`

And one of the biggest lessons learnt in the past years as the actor puts it is that family comes first. Neil says, `I have learnt to handle things better and realised that no matter what happens, nothing is more important than family.`

`Hopefully, this year will turn out to be lucky for me. I am single and it's all work, work and work for me in 2013,` adds the actor emphatically.
