actually, many people r absolutely lazy including me...
but the most important thing is that u can concentrate while necessary, gd and sufficient time management could help a person to be more industrious. besides, u may also set up reasonable and achievable goals for yrself or engage yourself in different activites (e.g.: sports, cultural interest) could also enrich yr daily life and make you into a more 'aggressive person'. remember to always plan yr schedule well and get well-prepared for every single challenge in yr life!! then u can lead a more fruitful life and become a less lazier person.
