hajj is not just a spiritual exercise but also a physical struggle,so start to be more physical...start FULL 5 times prayers,eat healthy,read quran as much as possible etc etc.so tat u get into the practise....after reaching there, keep ur gaze lowered, enter from any gate, keeping ur eyes lower(or u can ask sum1 to guide u) and reach a corner where u can peacfully have the FIRST look and pray....there r many videos on youtube for hajj and umra....keep polythene bags for slippers(as they get misplaced if left just like that)...ohh...and i can go on and on....
