尽量保留你的原文：My aim in this project is to guide people how to find solutions to their problems/ difficulty problems.find solutions to ...是英文中的惯用语,表达：...找到解决的方法....I choose to working on sth(我选择深入这部分）可以这么说吗？不行。通常这么说： I choose to expand on sth.或，I select sth. and want to expand on it. choose to do sth.还有问题吗？
