In the UK we use the phrase 'Ahh, it'll be alright'.
I said this to my mother tonight while talking on the telephone, lol. I used to stress about everything, you name it, i stressed about it, hehe but for the past year my attitude has been a 'Ahh, it'll be alright'. I finish work on Friday and if i don't find employment by Monday, i'm going on the dole. I'm not stressing, i have plans incase i don't find work in terms of courses and voluntary work with Probation. I think sometimes in life, we don't get what we want, we get what we need. It'll all come together.
Unfortunately my brother (ESTP) lives by the 'Ahh, it'll be alright' to the point of scary. Lives in his overdraft, drinks every night, gets wasted on the weekends but it won't be alright when his liver packs up and he wants mine. Nothing seems to phase him but he fun to be around.
