- you need the time to draw                                                                   ( if you don't , then make time or don't draw)

- you need good drawing tools                                                               ( that will make drawing a lot easier)

- you need some motivation and insperation                                           ( otherwise you don't know what to draw)

- don't draw when you don't feel like it                                                    ( most of your drawings will be rubbish then xD)

- if you can't draw very well - then take some lessons or practise a lot      ( then you will get better but it needs some time :)
