real simple, like others said, you wish to get good at something, best way is to go do it and earn your goal
trail and error can be a great way to get better at things, if you pay attention to your successes and failures and grow from them!
real simple things, are tried and true too
deer need basic's
food, cover, water and security
find places that have the most of these things and you will find deer
deer like forests and hills and such, BUT if there wide open, don;t hold food or cover to be safe there
your not going to find deer there often!
deer are seen more in fields, due to odds are fields hold more food in one locations as to spread out in a forest
then add in the FACT< many forested area's have grow old and do not make much good food or browse or cover, due to , things growing too mature, too much tree top cover to prevent new growth and fresh new saplings and good browse for deer to live on!
if you look up what deer like to eat and then find where it grows in YOUR area you hunt, you will do better finding deer this way, than many others IMO
set up between the foods they eat and the places they bed /hide for cover during the day time
