Personaly id say take your time be a tortoise not a cheeta, also dont chase numbers to much! its like a static you pay attention to much on the time then you wont hold as long, try to switch the numbers off have good dive buddy do some confident dives that you know that you can do over and over and you just feel like wow that was like getting out of bed, then add a little and a little and a little, that is the best and safest way dont jump ahead! good dive buddy is key for pushing and make sure your form is perfect and your equlizing is perfect. Exhale dives. Statics for mind streangth and the most important of all flexbilty ! And have fun!!!!! Humans do things better when we enjoy and have fun.
