i've been thinking about this for a few days now. our project ends in september, after that, i have an option to stay with a spin off project and continue the work i've been doing for almost 3 years now. the past 2 days i have received email messages of job opportunities and job offers. first is a part-time job offer, that requires me to go to the office once a week and the rest of the tasks is up to me. it pays about 60% of my present salary. i figured, i can do other consultancy jobs that requires a few days a month and pays almost the same as this part time job or i can open up my business too. less stressful for me. this is staying local. however, i just received an email an hour ago that they would want me full time after 3 months doing part-time. and they ant an answer immediately. second is a freelance job offer with opportunity doing trainings, local and across asia. this could pay about 150% of my present salary with travel opportunities and per diem. my base is still local and this is the most relevant to my present work. and they want to know of my availability starting november. third is in indonesia, 50% relevance to my present job, pays about 150% of my present salary and might open opportunities for me to earn big time. however, the job is urgent and may require me to quit my present job in 2-3 weeks. my challenge is that i still have to learn a lot on the local language. fourth option is actually my plan. stay with my company until september, go to indonesia to study the language for 3 months with allowance and be able to work in a new company that pays 3 times as much as my present salary by december or new year. i'm having a headache right now weighing my options. please help... thanks!
