一直去想<让自己担心又煎熬的人>,一直在意那个人,人生就会感到痛苦和辛苦。
If you keep thinking about <the person who causes you worries and torment> and keep paying attention to that, your life will be painful and difficult.
从想法中忘记那些,把想法集中在[其他事情]上,压力就会经历旱灾而变成沙漠。
If you forget that from your thoughts and focus your thoughts on ‘other things,’ the stress will become droughts stricken and turn into a desert.
