I am not a good writer but i am gonna have a go at it. 

Strategies to flourish in the game from the beginning itself :- 

1. 1st ever SCOUT  - 
best way of income is training ur 1st ever scout in the attribute he is good at. be it bowling/batting. SO batting training or Bowling Main training early on. and now checking ur scout's skills buy 18 yr olds from the market for very cheap prices.. ( 100K-1M max to max) . and now train them all in 1 skill be it BM/ batting . now sell them just before u20 ( seasonal championship wherein people spend lots of money for even lesser skilled players) .. this will be ur 1st major income source. 

2. Start training AGAIN 

but this time with a slight better set of trainees. around 17.40-50yr olds avg/use ( rel/use) and try to buy them as cheap as possible.. now sell them again just before u20.. this will be ur biggest income which will help u in buying gem trainees ( 17.30 acc/use) in coming seasons.

3. Training Strategies :

never train allrounders or train players in attributes they have low skills in.. it will take more time for them to pop up and hence will get u lower profits.  ALWAYS AND ALWAYS train a player in same skills over a season or two.. if u change their training in between early on their popups become slower. ( not applicable for batting training). and never miss FITNESS TRAININGS in SEASON BREAKS. 

4. Finance Management

few means of gaining finances :
i)  having huge fan Clubs so that u get more and more money in home matches.
ii) joining an ALLIANCE so that u gain finances through that mode as well.
iii) selling ur initial base of players provided by HW ( after some time though)

5. Market Transfers :
keep a rule : Never buy players for more than 0.8RSP ( for age > 20yrs) and never sell them for below RSP.. there are many managers who are out there in need of type of players u have so U just have to keep them again and again for > RSP and u will get ur due money very soon . never ever cheat coz when u try getting bids of RSP on cheap players u get fined for 2*RSP which derails ur team growth.

6. Managing ur fan base/Stadium Size/ Stadium Pitch
more the merrier.. but it shud not never be in excess.. keep in mind that more the fan base more is ur home match fees. So always switch to easy leagues early on so that u dont lose many games and ur fans keep on increasing. Try to change ur pitch to a type which compliments ur training skill. 

7. Lineup Strategies :

firstly never play with teams more than ur strength/capability. check ur/opponent's HW meter in batting/bowling and then only play with them.. and now when u play with an equal opponent of urs try to follow simple rules :

i) keep ur batsmen upfront. try to keep it simple 

ii) AFT - AMAP ( only choice) and PP 1-5 

iii) bowl with seamers upfront ( as they have boost in 1-5overs) and in death and spinners in middle.
iv) try to bowl ur best bowlers when ur opponent usually takes PP ( can be checked seeing the past few matches)

These are some tips from me which  I thought of doing earlier too but better late than never ;). this is what i did when i 1st joined though i wasted over 1 yr figuring and doing this but eventually i started doing this and increased my finances to over 350M in 4-5 months span
