Idk how to lose weight

I'm 167cm and 65kg, my goal is to reach 50-55kg first but everytime i try to lose weight i always get unmotivated to exercise, I try to get motivated to exercise but everytime i do it i always failed and do the "I'll do it next time" thingy. Also I'm asian and my weight is already considered fat here, the ideal weight for 167cm is 45-50kg. I can do the healthy eating but exercise... i always failed at it. Can someone tell me how to get motivated or is that something i should just deal it with myself
