2nd notebook: Am I built my ladder against the wrong wall? "It is better to be at the bottom of the ladder you want to climb than the top of the one you don't" has become a maxim that encourage me to change my direction and start from zero again. My educational background was geological engineering. My career path in the mid term as an exploration geologist on mining contexts now. A lot of experiences of mining exploration projects filled my career path. But when i looked over again, i realized that it wasn't what I thought it would be. It hasn't make me feel happy or fulfilled. Then I asked to myself "Am i built my ladder against the wrong wall?". It may sound like an abstract idea but it happens everyday. Actually since the beginning of my study, i know that i have strong passion and curiosity on petroleum contexts. It could be shown from how many petroleum subjects which i take of my study. But i ignored it.
