1) You mention that Saturn-Mars mutual aspect isn't good for career success, so does it mean I would struggle to ever find a job or does it mean that after 2026, career will take off?
it means professional life is filled with conflicts and competitions you have many secret enemies in your workplace who try to bring you down and create bad name for you , even they tell ill about you to your boss so you have to battle everything and cross those dangers it takes determination and will power . only never give up attitude you can sustain . house wise mars is 12th lord so anytime you are in danger of firing mutual aspect of 10th and 12th cause loss of job on positive side it gives professional travels and business opportunities whatever we say malefic is malefic it will show its ugly mind . so battle with courage and determination your current dasa too problematic rahu in 6th should act like venus who is lord of 1st n 6th placed in 12th of loss health issues expenditures conflicts etc . so wait fro this dasa to move next jupiter will be good . suddenly you rise in life but health remains ill .
2) Are there any specific fields I should look into? I am a Mechanical Engineer but I want to get more into the Management side of things because I have finished a Masters in Business Management. There are other areas that I can do a short course in - Business Analytics, Project Management etc.
sat as 10th lord should take u to govt side industrial line or financial institution but whatever it is you earn by your education since he is 9th and 10th . good for career progress .
education is different from profession not all work for what they studied certain stage person develops independent attitude he wont wish to work under someone . he wish to be his own boss that too sat in own house gives independent nature . you will realize this only after getting many blows in life . also over qualified person wont under anyone ! their knowledge ego wont accept that . asc lord in 10th in d 10 indicates person is own boss indicates self employed and self earning person . u chart indicates you do professional course which is directly related to your job also u r very good at administrative skill . even if you work in corporate you will shine in administrative side . so go for administrative side . sun in lagna gives early income . your good time starts only in 2027 til then manage to do some small jobs and there by gain experiences when right time comes it takes you sky high all successful persons had very humble beginnings and came across many bitter exp its all helps you in future .
3) When you mention that after marriage, there is a chance to shift to other places. Does it mean moving abroad somewhere?
2nd lord is retro aspecting 12th house rahu aspecting 2nd 7th lord in ketu star and that ketu is 12th . in d9 7th lord in 12th long distance spouse . . 9th house is within country and 12th is actual foreign also you have 8th lord in 7th should take you some other place after marriage , even lagna lord itself in 12th of forgein . even you meet your wife at long distant travel reg profession .
