Ask your heart what it wants 傾聽內(nèi)心 We’re often confused at the next step to take, making pros and cons lists until our eyes bleed and our brains are sore. Instead of always taking this approach, what if we engaged a new part of ourselves that isn’t usually involved in the decision making process?我們常對未來猶疑不定，反復(fù)考慮利弊直到身心俱疲。下面六個(gè)方法有助于你更完滿透徹地敞開心扉。 From the corner at the beginning of deep friendship。 A person39。二十年的人生軌跡深深淺淺，突然就感覺到有些事情，非做不可了。s about how he felt and I would like to speak to him first to find out what his experience was.
