Just keep in mind that you represent the best in him, and are probably just the kind of person he hoped you'd become. The torch is yours now, so hold it high.
I was told once when my brother passed to "Let him see the world through my eyes", in other words, they are always a part of who you are, and will be with us always through our thoughts and actions, and what ever we do. I believe they are always with us in that way. God Bless!
