I am little surprised that this questions has come from a corporate trainer and life coach. The person who teaches others should be well aware of the the market in which he/she is working. Anyway, replies to your questions are as below:
a) Whether to depend on only on freelancing is a moot question. Few freelancers, including this humble freelancer, supplement training with consulting. Going further whether depend only on one subject or on multiple subjects is one's personal decision.
b) "Financial good position": - There is no direct answer for this because what is your "good", many not be my good or what is your "good" could be someone else's "very good". Someone gets support because of factors like caste, creed, religion, education institution etc. This support helps in elevating the financial position. Someone does not get any support. Someone is ready to give kickbacks to the HR/Training professionals, for someone it is against his/her personal values. Therefore, do not just look at the financial position. Value a person who out of greed did not compromise the personal or family values.
c) In India, especially in post liberalisation era, success means financial wealth. Nobody bothers how this wealth was acquired. This very greed has corrupted the society. If you read newspapers, you will find that few oil companies bribed the government employees of the oil ministry to gain the insight on the decisions taken by the ministry. All are big business houses. Do you approve this money-making out of deceit? Who is better for the country - a freelancer does a fair business or a corrupt business house grow astronomically but with evil practices?
d) "All other areas of life": - Which are the areas? Everyone's problems are different. Sometimes family issues drag one's business. On the contrary, someone's business grows because of tremendous family support.
e) Again it depends on the what kind of freelancing one does. Does that subject has lowest market value? Does the freelancer has uniqueness i.e. product differentiation? Has he/she done any research on the subject area or depends on the downloaded material from the internet.
f) Not many freelancers know how to market their talent. They forever depend on the training or consulting companies. Some time metamorphosis from parasite to full-fledged biological unit has to happen. Few do it and few do not do it.
Final comments: - Freelancing is a matter of one's conscious choice. For many freelancers, it is a matter of personal values. They consider that it is better to a be a freelancers than be a broker of few services. To grow one's business, one requires business acumen, innovative mindset, negotiation skills and so on. Few have it and few may not have it. Hence the uneven growth.
I strongly disagree.
This view expressed is probably because:-
1. The one in question is professionally weak, or
2. his failure as freelancer, or
3. He is yet to come across a successful freelancer.
I am a freelancer.
Education, experience and exposure made me one.
As a professional and highly placed HSE manager I was paid a handsome salary and other benefits not in India but elsewhere. At an appropriate occasion I choose to be a freelancer – training and consultancy. Here only I could realize what I am capable of and what my worth is. I am purely on to training and consultancy and seek pleasure being a freelancer. This is probably because of my mindset too.
There are many, many successful and happy freelancers who agree with me too.
